Running `rails` on Ubuntu executes Rails 2 even after installing Rails 3

view story
linux-howto

http://askubuntu.com – Previously, I ran apt-get install rails, but that only installed rails 2, so I subsequently ran gem install rails. The output of that command clearly references rails 3, not 2: Fetching: railties-3.2.9.gem (100%) Fetching: bundler-1.2.3.gem (100%) Fetching: rails-3.2.9.gem (100%) # ... ...but rails -v outputs Rails 2.3.14. Gah! I can't run my rails local server! Yet when I run gem list rails, the output is: *** LOCAL GEMS *** rails (3.2.9) What am I to do to get the rails 3 rails command to work on the command line? (HowTos)

Terminator can't find Rails 18 weeks 4 days ago

I started using Terminator, the teminal emulator, but when I run a rails application it can't find Rails.

humberto@asterix:~$ rails -v The program 'rails' can be found in the following packages: * rails * ruby-railties-3.2 Try: sudo apt-get install <selected package>

Does anyone knows how to solve it?

Using paperclip (3.2.0)

Using polyamorous (0.5.0)

Using pr_geohash (1.0.0)

Using slop (3.3.3)

Using pry (0.9.10)

Using pry-rails (0.2.2)

Installing Rails on Crunchbang 45 weeks 5 days ago

Are there any Ruby on Rails developer here?I want to learn Rails and setting it up on Crunchbang  is proving to be a major pain. I think most Rails developers are using Mac OS X instead of Linux. After hours of googling (many of the information are out of date), I gave up andinstalled it in 5 minutes on Win7 using http://railsinstaller.org.

Ruby on Rails missing Thor 29 weeks 1 day ago

When trying to run rails g migration a, I get the following message

Thor is not available. If you ran this command from a git checkout of Rails, please make sure thor is installed, and run this command as `ruby script/rails

Now few days this did work, and I did check my gemfile and I find thor like this

I just switched from Heroku to Amazon Web Services. Previously I ran all of my Rails command line commands using my Command Prompt with Ruby (from my Windows PC).
